  • Title: [Induction of lipid peroxidation in the erythrocytes during cholesterol oxidation catalysed by cholesterol oxidase].
    Author: Kagan VE, Monovich O, Ribarov SR.
    Journal: Biull Eksp Biol Med; 1985 Aug; 100(8):179-81. PubMed ID: 3861201.
    Abstract:
    Using the chemiluminescence technique to assay the activity of cholesterol oxidase it has been shown that enzymic oxidation of cholesterol to cholest-4-en-3-one red cell membranes is accompanied by accumulation of lipid peroxidation products--malonyl dialdehyde (MDA). The amount of MDA formed was dependent on the amount of cholesterol oxidized. The free radical scavenger 4-methyl-2,6-ditretbutylphenol, the transition metal chelator EDTA and catalase inhibited lipid peroxidation in red blood cells. The participation of OH radicals in the initiation of lipid peroxidation in red cell membranes in the course of cholesterol oxidation is discussed.
